With the aim of building an independent space infrastructure for Japan, IHI has begun operating 2 synthetic aperture radar satellites from ICEYE. Plans are also advancing for new launches involving domestic assembly, with a constellation of up to 24 satellites in view.
IHI has begun operating 2 synthetic aperture radar (SAR) satellites procured from ICEYE, bringing satellite data collection into full operation. Their ability to provide high-resolution data day or night and regardless of weather conditions is expected to support national security applications, including maritime surveillance and monitoring of critical infrastructure.
Under the contract, 4 satellites have been confirmed for procurement based on the agreement signed with ICEYE in October 2025, with the longer-term aim of building a constellation of up to 24 satellites, including an additional 20 available under options. In addition to the 2 already in operation, the sequential deployment of follow-on satellites will drive the plan forward.
The remaining 2 satellites are scheduled to be assembled and tested in Japan around summer 2026, with their launch expected in the fourth quarter of fiscal 2026. This is expected to expand observation frequency and imaging capacity while strengthening the infrastructure for continuous data provision.
Looking ahead, IHI is considering the integration of a range of satellite sensors, combining optical sensors with VDES, RF, IR and hyperspectral technologies. The company has indicated a policy of securing space infrastructure originating in Japan on an autonomous basis while leveraging international partnerships.
